Abstract
Arterial selection for reference time-enhancement curve generation in deconvolution-based perfusion CT (PCT) studies of the head and neck is under-evaluated. This study of 11 patients with confirmed head and neck squamous cell carcinoma demonstrates significant correlation (range, r = 0.85-0.95) between perfusion parameter values derived with internal carotid artery (ICA) as compared to an external carotid artery reference, supporting the use of the ICA as arterial reference in PCT studies of the neck.
摘要
在基于去卷积的头颈部灌注CT（PCT）研究中，用于生成参考时间增强曲线的动脉选择尚未得到充分评估。这项对11例确诊的头颈部鳞状细胞癌患者的研究表明，与颈外动脉参考相比，以颈内动脉（ICA）得出的灌注参数值之间存在显著相关性（范围，r = 0.85 - 0.95），支持在颈部PCT研究中使用ICA作为动脉参考。
